This wasn't covered by the course for me. I'm only familiar with the word husband
i am also very tired, but will be awakened by the sound that appears after i make this post
Just to note: The word تعبان is more colloquial. The proper Arabic word would be تَعِب (ta3ib) or more commonly مُتْعَب (mut3ab).
The course is designed to be a formal colloquial dialect which can be spoken and understood in most formal-casual settings. It is not meant to teach the most formal version of the language. For that, you need a teacher.
All over the world, Arab people understand and appreciate the formal version of the language.
